In the February issue of “Modeller-designer” we met article on the development of a new class of car — unmanaged vetrogonov. Don’t know how reacted to the most interesting suggestion of the authors of that article and the magazine automodeling Federation of sports of Russia, but in our circle it was accepted “on hurrah” — so interesting, affordable and promising was this topic. Work on a new type of machines we started with, that surely will be useful to all, tion interested in constructing vetrogonov — with the development of minimized similarity of the internal rules of the competition and technical constraints applicable to unusual models. On the last point we were limited to only the maximum area of the driving model sailing arms (no more than 25 dm2) and the total dimensions of the machine (prepared by the start condition, it must fit into a cube with sides not more than 1000 mm). Under these constraints, Verkade should be potentially very fast and quite “personable” for forms that will go only to the benefit of the attractiveness and popularity of the competition in the new class. It should be noted that the rough calculations of the maximum potential speed of movement convinced us in the fact that would be very useful, additional development is reduced “oneorzero” type vetrogonov. Here are our suggestions tanovi: sail area limit of 10-15 dm2, and dimensions described Nuba 500-600 mm.
Think about creating a “Junior” division, we made the information derived from a very interesting and useful book by Joseph Norwood “Fast sailing ships” (published by publishing house “Shipbuilding” in Leningrad in 1983, is translated publication we recommend to everyone who is passionate about sailing theme). There is a number of calculations and decanters, claiming that the potential rapidity of sailing of ice boats, or similar characteristics of our vetrogonov can reach eight times the magnitude of the wind speed. This means that, in principle, if the wind is 10 m/s on a perfectly designed and made
car with special wheels to the perfect site achievable speed of 288 km/h!!! Of course, it is rather pink dreams, but this amount legitimately be considered and the level to which it is not only possible but also need to strive for.
Parallel calculations of the loads on the sailing equipment, also gave very interesting results. It turned out that when given the perfect speed wind load can reach the level.
